Bind update for SL4.0

[Gerry Pyne]

Sorry for the mis-info on my last post - The version of bind on my SL 4.0
box is actually bind-9.2.4-28.0.1.el3.i386 and yum says there are no further
updates for this. My dns is showing "poor" when I run the test.  If I look
at updating bind to a later version there are many dependencies that need to
be updated as well and so I was hoping there may be further updates /patches
for this version - or is my only choice to update altogether to something
more current?
